Embodiment 1

[0027] like figure 1 and figure 2 As shown, a rotary installation structure of a battery pack of the present invention includes a power unit 1 and a battery pack 2 movably connected to the power unit 1. For better description, the power unit 1 in this embodiment is a portable The power tool, wherein the battery pack 2 is electrically connected to a pair of power electrodes 4 of the power device 1 through a pair of battery pack electrodes 3 correspondingly, and a positioning hook 5 is provided in the middle of the docking surface of the power device 1, which is connected with the positioning hook. 5. A positioning slot 6 is opened on the outer casing 21 of the corresponding battery pack 2. The battery pack electrode 3 and the power electrode 4 are arc-shaped members with the same shape and size, and the battery pack electrode 3 is located on both sides of the positioning slot 6. , the power electrodes 4 are located on both sides of the positioning hook 5, and the two battery ...

Embodiment 2

[0034] like image 3 As shown, a positioning hook 5 is provided in the middle of the butting surface of the outer casing 21 , and a positioning hook 6 is opened on the abutting surface of the power device 1 corresponding to the positioning hook 5 . The rest is exactly the same as in Example 1.

Embodiment 3

[0036] like Figure 4 and Image 6 As shown, the outer ring surface corresponding to the outer end of the positioning column 51 is integrally extended outward to form four square positioning bosses 52 , and the inner side surface of the anti-loose washer 7 corresponding to the positioning bosses 52 extends toward the interior of the battery pack 2 to form There are four spherical elastic bumps 62, and the height of the elastic bumps 62 is 0.5 mm to 1 mm. When locking, the positioning hook 5 is hooked on the corresponding elastic bumps 62 through the positioning bumps 52, in order to prevent the locking position from being deviated. , the limit posts 11 are set at the initial locking position, and the limit posts 11 are all located on the inner wall surface of the outer casing 21, wherein the anti-loose washer 7 is made of metal material, and the anti-loose washer 7 and the outer casing of the battery pack 2 21 A spring washer is installed between the inner walls. This embodi...

Abstract

The invention discloses an installation structure of a battery pack, provides a rotary installation structure and an installation method of a battery pack with simple structure, convenient and quick disassembly and assembly, low electrical loss, and safe and reliable electrode connection, and solves the problems existing in the prior art. The contact area between the connecting electrodes is small, and the electrodes are easily heated and cause safety accidents when the current is large, and it is easy to cause technical problems such as poor contact between the electrodes, which affects the normal use of the power device. The battery pack on the device. The battery pack is electrically connected to the power electrode of the power device through the battery pack electrode. The docking surface is correspondingly provided with a positioning hook and a positioning slot, the positioning hook extends into the positioning slot and is rotated and then hooked and fixed, and the battery pack electrode is sealed and pressed on the power electrode.

Description

technical field [0001] The invention relates to an installation structure of a battery pack, in particular to a rotary installation structure and an installation method of a battery pack with convenient and quick disassembly and assembly and safe and reliable electrode connection. Background technique [0002] The electric blister pack is an important part of the lithium electric power tool, which provides power energy for the electric tool. In order to be easy to carry and use, the electric blister pack usually needs to meet the conditions of small size, simple structure, and convenient disassembly and assembly. The existing electric blister pack fixed connection generally adopts the in-line type, that is, the blade-type electrode of the electric blister pack is inserted into the clip of the electrode insertion spring of the electric tool, and the blade-type electrode and the electrode insertion spring are in point-line contact. The contact area of ​​the two is small, the c...
